Overview of this book

The beauty of Ruby is its readability and expressiveness. Ruby hides away a lot of the complexity of programming, allowing you to work quickly and 'do more' with fewer lines of code. This makes it a great programming language for beginners, but learning any new skill can still be a daunting task. If you want to learn to code using Ruby, but don't know where to start, The Ruby Workshop will help you cut through the noise and make sense of this fun, flexible language. You'll start by writing and running simple code snippets and Ruby source code files. After learning about strings, numbers, and booleans, you'll see how to store collections of objects with arrays and hashes. You'll then learn how to control the flow of a Ruby program using boolean logic. The book then delves into OOP and explains inheritance, encapsulation, and polymorphism. Gradually, you'll build your knowledge of advanced concepts by learning how to interact with external APIs, before finally exploring the most popular Ruby framework ? Ruby on Rails ? and using it for web development. Throughout this book, you'll work on a series of realistic projects, including simple games, a voting application, and an online blog. By the end of this Ruby book, you'll have the knowledge, skills and confidence to creatively tackle your own ambitious projects with Ruby.

Summary

This chapter aimed to provide you with the knowledge necessary to create modules with the Ruby object model. We have added instance methods by including modules into classes. We have added class methods to extend class functionality. We have created namespaces for our modules. As a very crucial part, we have made a distinction between prepending modules into classes and how you can extend and include functionality. Modules in Ruby accomplish multiple purposes such as creating namespaces, creating reusable class and instance methods, and modifying a class's code at runtime. Modules are Ruby's answer to multiple inheritance, in that they allow classes to incorporate code from multiple sources. As we saw in the last section, when a module is included or prepended, it affects the class hierarchy, which is what Ruby uses to do method lookup and dispatch. The ordering of this hierarchy is important and something to keep in mind as you start using third-party modules in...
